I've designed a board that has a STM32L476.This part is supplied using a triple system of dual battery + power ( when it is available)We've manufactured more than 20k units of them and they are working okA few days ago 2 boards came back to our desig...

Posted on July 17, 2015 at 10:58Hello, I'd like to know if there is a 'magical' way to syncronize the bit stream with the channel signal in the i2s receivers. I don't have control on the external stream ( slave mode), so the serial clock is free run...

Hi againJust in case anybody has the same problem :The HAL lib doesen't mask the bit fields before writing the data to the RTC registers, so any stray 1s in the variables outside the defined fields will corrupt your RTC register's data.The solution i...

Hi JWI got sidetracked with other more important tasks, but yesterday got on it again.I've been able to reproduce it by setting the date/time a few 1000s of times, and it could be an uninitialized structure member when calling HAL_RTC_SetTime.The str...

Hello JWOnly on the problematic board :-> after 12:59:59 the RTC becomes 13:00:00, the day don't gets increased-> after 23:59:59 the RTC becomes 24:00:00, the day don't gets increased-> after 39:59:59 the RTC becomes 00:00:00, but the day don't gets ...

Hello JW1st : Thank you very much for your interest in this question. Your help is greatly appreciated.Now, on to the symptoms :A - The MCU is connected to an FPGA that has a PCIExpress interface. I can access in real time the MCU and ask for a limit...

Dear JWThe code that sets the RTC explictly sets it as 24h format : __HAL_RCC_PWR_CLK_ENABLE(); __HAL_RCC_RTC_ENABLE(); /* Configure RTC */ hRTC.Instance = RTC; /* Set the RTC time base to 1s */ /* Configure RTC prescaler and R...
